SLIDNG ADJUSTABLE WINDOW-SCREEN..

SPECIFICATION forming part of Letters Patent No. 597,627, dated January 18, 1898.

Application iiled August 4:, `1897.

To @ZZ wiz/nmv t may concern:

Be it known that we, RICHARD VEBB and EDWARD E. SoHoENINe, both citizens of the United States, residing at the city of St Louis, in the State of Missouri, have invented a certain new' and useful Improvement in Adjustable Sliding lVindow-Screens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specilication.

The object of our invention is to provide a window-screen that is capable of being adjusted to a window of any size and which when adjusted may be rigidly secured in place. It is so constructed as to leave no spaces either between the screen-sections or between the window-sash and screen-frame to afford the ingress of iiies or other insects and possesses features of novelty hereinafter fully described and claimed.

Referring to the drawings which form a part of this specification, Figure I illustrates a front elevation of our screen in position, while the windev-frame is shown partly broken away. Fig. II is a detail rear View of a portion of the horizontal bars. Fig. III is an enlarged section on line III III, Fig. I. Fig. IV is a horizontal section taken through the screen-netting along the line IV IV, Fig. II. Fig. V is a detail longitudinal section taken along the line V V, Fig. I, showing the manner of securing the horizontal bars of the screen to each other. Fig. VI is a detail cross-section taken on the line VI VI, Fig. I. Fig. VII is a horizontal cross-section taken along the line VII VII, Fig. I. f

1 is the window-franie 2 is the window-sill, and 3 the sash.

at are the two vertical side pieces of our improved screen, which are furnished with grooves, in which strips 5 are adapted to it, the said strips being secured in the ordinary manner to the inside of the windowfraine l.

6 and 7 are the horizontal upper and lower bars, which are supplied with dovetail Inortises 8 and 9 and are adapted to set close to each other and admit the insertion of blocks 10, each of said blocks being made to lit snugly into the said mortises S and 9 and yet being capable of 'xnovingtherein Each block serai No. 647,110. (no mais.)

is channeled, so as to he incapable of removal from said lnortises in any way except longitudinally.

11 'are thumb screws adapted to pass through the bars (i and enter the blocks l to securethe same in any desired place. 12 are washers placed between the heads of the said thumb-screws and the said bars 6.

13 are tenons secured to the inner ends' of the horizontal bars 6 and 7 and so flared as to ride in the mortises S and 9.

14 is the screen-netting connected to the bars 6 and 4:, and l5 is the screen-netting connected to the bars '7 and 4.

16 is an angle-strip secured to the exposed edge of the screen-netting 15, one edge of which is bent inward ly at a right angle thereto, so as to come snugly against the netting 141.-, thereby avoiding any open space between the two sections. 17 is asimilar angle-strip secured to the exposed edge of the screen inaterial 14.

18 is a guard or cap bent at right angles and fastened by any suitable means to the upper horizontal bar 6 and' bent over the line of the horizontal bar '7, so as to close the space between the end of the bar 7 and the window sash.

The device is operated as follows: The strips are secured to the window-frame l in the usual manner. They are adapted to act as guides in raising and lowering the screen, the side pieces 4 of said screen being provided with grooves that lit such strips for that purpose. The screen is placed in position with the guard or cap 18 on the outside and the thumb-screws 11 on the inside. The screen is first drawn together with the tenons 13 riding in the mortises S and 9 and the blocks loosely riding in the mortises S and 9 and the thumb-screws 11 in position. It is then spread apart until it snugly fits between the guide-strips 5. The thumb-screws 1l are then turned into the blocks 10, which operation causes the blocks 10 to hind in the dovetail inortises and the bars 6 and 7" to be drawn closely together and secured in the required position. The tenons 18, fastened to the bars 6 and 7, act as guides for the inner ends of the bars 6 and 7. The space between the two sections of the screen-netting is lled by the inturnedangle of the strips 16 and 17, (see Fig. IV,) which vare secured to the eX- posed edges of the screen material 14 and 15, as heretofore described. The space which would otherwise be open between the end of the horizontal bar 7 and the upright bar 4 is horizontal bars 6 and 7 are coincident with each other and thereby form a guideway for l the block 10, into which the thumb-screw 1l is introduced, and provide a construction by means of which the two pieces may be secured together with absolute rigidity. This object is furtheraccomplished bynse of the blocks 13, which are securely fastened to the inner ends of the bars 6 and 7, which are widened so as to be retained in the mortises in the bars 6 and 7.v This construction accomplishes the desired result of keeping the two screen-sec tions tightly together.

We claim as our invention-- The combination consisting of two screen# sections; a means of adjustably securing the same together consisting of horizontal bars adapted to ride coincident to each other and each providedwith a dovetail mortise, movable blocks riding in said mortises, thumbscrews passing through said bars and enter ing said blocks, `tenons secured in the ends of said mort-ises of the bars of one section and riding in the inortises of the bars of the other section, inwardly-turned angle-strips secured to the exposed edges of the screen material; and an angle guard or cap fastened to one of said horizontal strips and adapted to close the space between the end of said other horizontal strip and the window-sash, substantially as described.
